How to solder like a pro, Tutorial for trainee plumbers or gas engineers on soldering correctly.

Derek in this video shows DIYers and trainee plumber and gas engineers how to solder horizontally and vertically like a professional.

[@LittleShadowWoodcraft]

This is not just about soldering. It’s a fantastic tutorial on this and a host of other tips, techniques and things to consider. Thank you so much for sharing this!

[@tonesmith909]

Holy Grail of copper soldering tutorials.

[@tarunarya1780]

This video is the best most comprehensive one I have seen.I have seen lots of videos though not really implemented what I learned and refereshing my unpracticed memory due to leaks. I thought it was really great, clear and concise.Thanks for your excellent work.

A good point for new folks, is when fluxing the pipe, try to match the insertion depth of the fitting e.g 22mm pipe fitting maybe 1" insertion, so Flux an inch on the pipe, it helps identify whether you have full insertion (only a thin line will be on show once pipe is slid in) . This is good practice especially for awkward / multiple fittings assembled at one time before soldering. I apply solder with flame on opposing side, then remove the flame and almost cool the joint slightly with more solder, otherwise, especially on horizontal fittings, the solder sinks down the joint and you get almost a recess in the top of the joint. Taking away torch and adding solder while joint cools, it'll solidify very quick and stop that. Do not try to be neat soldering for the sake of it, to avoid having drips and adding not enough solder, so a joint pops, you'll kick yourself and never do it again.

[@southeastgasservices]

biggest tip is . copper and fitting must be spotless. If copper is gone dirty brown form sitting on top of the van for about six months. or it's just old copper, the best way to clean it is to apply some flux, heat the pipe till the flux starts to run, them immediately apply wire wool around the area to be cleaned, clean off immediately with a cloth. the copper will be spotless, guaranteed perfect joint.

[@whitefields5595]

It would be useful to show capillary action by putting two flat pieces of glass together in dyed water. It is not 'attraction', but the interaction at a molecular level between the fluid (solder) and the solid surfaces provided the gap is small. Once trainees 'get' this they will not be mystified as to what is happening inside the joint when soldering uphill. This gives them the confidence not to overfill. Also emphasise that the wire wool is mechanical cleaning, the flux is chemical cleaning/oxidation prevention. Good vid.

[@Heatingandplumbing1]

downfall of soldering is I found that it bags my lungs up and that ever flux fumes sticks to your skin.. they've found soldering causes industrial asthma. I moved over to press fittings and using a novopress gun. feel much better after installing boilers. not soldered in 3 plus years now. Nice video Derek.

[@bodinian]

Darn, now you have me concerned. I think if I did this as a profession I'd go for press too since it looks nice and there's no risk of fire; air quality is an added bonus.

[@joaquinsanabria2734]

Great video. Thanks a lot from Colombia.

[@wackypeace1135]

Best honest tutorial

[@andrewtomlinson18]

If you’re new to pipework and soldering just get yourself a few lengths of 15/22mm copper pipe/fittings and just practice horizontal/vertical and overhead soldering And don’t forget safety glasses.

[@amirvakilian1248]

Professional video as always 👍🏻 Always enjoyed to watch your videos. Thank you

[@ashvanbro9329]

Another great video mate like always i always use mapp gas never had no problems

[@phillipzammit454]

Great video, awesome 👌

[@stevee6316]

Interesting demonstration.

[@mohindersembi7647]

Thank for your reply I am very sorry to disturb you as you very busy as you mentioned I checked the d.5 is 56 and d.71 is 75 on my heating system I am using smart Honeywell EVOPACK4 Evohome Base Pack & 8 HR92 Multi-Zone Heads with touch screen displays system

[@tomkatgastraining]

For what you are saying it looks like it’s the controls obviously I am not in front of the boiler but it’s the first thing I would check

[@g1sh657]

You are amazing thanks for sharing this information .

[@mohindersembi7647]

Wow very nice video 5 star you are the best professional engineer and the master 😀 I been watching all your videos and gave you thumbs up please kindly help me on my vaillant ecotec plus 837 R1 bolier the problem is it goes not goes on slow burner flame ? On central heating and they are no fault error message the boiler and it fires 🔥 up goes to set temperature ie 60 °C and then cut out and the temperature drops to 34 °C then its start after 4 minutes again and keeps doing this again and again?all the radiators are working fine and the boiler keeps on doing this ? Why is it ? Can you please kindly help me on this issue waiting for your kind reply Thankyou 🙏

[@tomkatgastraining]

Is the boiler too big for the heating system

[@rayc1503]

Basically your boilers hitting temp and cycling on and off. Is it making a strange sound? Possibly a partially blocked heat exchanger.

[@johntchb]

I havent soldered in decades but have a few jobs that need doing.l am going to get a bit of 10mm pipe from coil. yorkshire straight couplers connectors and do a bit of re cap practce before doing the job.need to buy a good solder mat as the present bathroom has a marble effect veneer ,theres a switch to a double rad same size.what l really want to know is with a medium gentle flame will l notice the speed variant much, l only done 15 and 22 previous.thanks for all your advise.

[@andrewbrinkman9732]

want to extend pipe out of wall for bathroom rad if I cut olive off wil a Yorkshire fitting be OK as pipe is slightly squashed

[@andrewtomlinson18]

You should put together a rogues gallery of the worst soldered joints you come across.

[@connoraxelson1]

While I'm at it, that vertical steaight at 24 mins, you should've shifted the torch down to the bottom joint and fed solder from. Above, neater and better 😁

[@indysingh6547]

Thanks

[@tommiller1315]

Copper & Zinc? Thought it consisted of Tin & a small amount of Silver, (& or Copper). I use 60 / 40 Lead / Tin, as that is all I have from my electronics days. I do have a roll of thick lead free and hope to learn how to use that now...

[@binagarten4667]

The supply to my house is a lead pipe and then they wont let you use lead on a small fitting!

[@gadasavideos8564]

at 15:40 what is flame on , the pipe or the elbow coupling?

[@peterreid4567]

Quick question. You should not use everflux on gas. Or around the gas meter ect. It’s not a great idea causes a lot of leaks later on.

[@peterreid4567]

Also I was told don’t ever flux inside the fittings. Would you agree

[@tomkatgastraining]

Yep but if I said I didn’t do it I would be a liar 🤥

[@alec1113]

Brilliant education , have you tried tinning flux

[@Vincerama]

I think MAPP gas has been discontinued for quite a while hasn't it?

[@johnward5006]

Useful video, I personally only use lead free, purely because it saves changing solders when working with a mix of services. Many years ago, I suffered a severe reaction when flux on my shirt collar rubbed against my neck. Apparently the flux contained a form of hydrazine. Just being pedantic, when describing tees, it's ends first and branch last. Could you do a video that explains how spring return valves maintain the various positions. I recently discovered a video on the subject by my namesake (no relation!). I've been fitting spring return valves 50 odd years and never knew what I found out. I'm sure I'm not the only one!

[@tomkatgastraining]

Yeh when I was filming it I said the tee size correct first then I thought DIYers would get confused so changed it. You just can’t win 😂

[@johnward5006]

@@tomkatgastraining Even the merchants don't always know, but that was the way I was taught! In other parts of the world they describe as you did, but in the UK my way is correct, let the DIYs learn this.

[@tomkatgastraining]

@@johnward5006 you are correct but most go to b and q anyway 😜

[@johnward5006]

What I learned about spring return valves, was that in conjunction with switching and electronic components, the motor is supplied with DC current which stops the motor turning and holds the valve in the desired position. Now I've shared this, I hope we can keep this knowledge away from electricians!

[@jezlucas3878]

Brasso pipes to look perfect doesn't get me excited either

[@mohindersembi7647]

Wow thank very much for you very quick reply I have 7 radiators double panel double converter radiators and I have checked the NTC SENSORS they are reading around 1300 at 20 °C and I have reduced the the valiant boiler out put to 12 kilowatt on diagnostic mode "d.0" = 12 kilowatt and it still the bolier doing the same thing goes to 60°C and cuts out and the temperature on bolier goes down to 34°C and its start again and keeps on doing this as you are very professional engineer any ideas what's going on with is bolier please kindly help me on this issue waiting for your reply Thankyou 😊

[@tomkatgastraining]

If you go into d 005 what is the target value set to

[@tomkatgastraining]

Also what is d071 set to

[@tomkatgastraining]

Also what controls are you using

[@the1beard]

my parents house was fitted with central heating in 1972 all copper pipes with lead solder still going strong in 2023 50 years trouble free will probably go for another 50 years Plastic compression etc isn't as good imho

[@Vincerama]

I find it funny that in the US, we have blow torches and flashlights and in the UK they are blow lamps and torches.

[@QUIX-KIWI]

@Vincerama, it isn't funny at all, as the GREAT AMERICAN DREAM wasn't to "BE FREE", but to be FREED from old English customs and sayings, so they decided to do and say EVERYTHING arst about, to ensure they were recognized as.. Yep - "Inverted English", thus of English origin, butt not now Old English, just New English, or just plain "A-Merry-Can's". Hence why Carrots became Root Vegetables, Fahrenheit, became Celsius & the Pound became a Dollar. And a NOTE became a Greenback (as if it was a different colour on the FRONT Oh and Colour (English spelling) was converted by dropping U out of it, to become Color - (as if it was a Colonoscopy issue?) BUTT That's just FOUR Shytz & Giggil(oh)s . USA means "Udderly Stuffed A-holes."

[@chazzlebazzle69]

I still do the odd copper to lead repair until the customer can afford a full copper refurb

[@johntchb]

That's a skill that few men can do mowadays👍

[@jockster5525]

Great job 👍👌

[@keithbrueton]

That map gas is struggling there Derek 24:15

[@Pro.1322]

Now your customers know to check the back of the pipe after you’re done 😅

[@jasnapon]

Heard no more map gas it's all the same 🤔

[@SuperWayneyb]

🤘😎🤘

[@truthseeker7794]

The camera work was quite poor on the first soldering demo and didn't show the positioning of the flame on the fitting, the colour change of the fitting and the pipe, the bubbling of the flux, the melting of the solder and the capillary action when the solder was sucked in.

[@wazuo8354]

I'm thinking of buying a new gas cooker, currys charge £110 for 'expert installation', sounds like they just screw in the gas pipe, is it worth the money, should I do it myself, ask curry's to do it or get a gas engineer out ?

[@user-xu2hv6tw8l]

Engineers know best - they have trained hard for a year to be able to make that gas appliance safe. You should also get appliances checked annually.

Yeah but professional plumbers are not watching this, we don't need details, KZbin videos are searched videos. Therefore STRAIGHT to the point 👍

Love how most of the plumbers feel the need to throw low key shade at Lee for cleaning and polishing his work and think we don't see. I like polished pipes, i don't care if they are boxed in. It shows pride in ones work. I'd choose Lee over any plumber on here. M J tiff is messy as hell and doesn't clean anything. Not for me.

[@tomkatgastraining]

Who’s Lee ?

[@forrest8507]

What the hell is a mm? Is that some kind of gay/liberal inch?

[@MrMedicalUK]

Its not capillary attraction and it has nothing to do with metals heating

[@tomkatgastraining]

I think you will find it is

[@MrMedicalUK]

@@tomkatgastraining errrm no.... Capillary action, commonly known as capillary effect or motion, is when liquid flows through narrow spaces without external forces, such as gravity; rather, the liquid's movement is aided by intermolecular forces present in between the liquid and solid surface(s).

Just got a distinction on my exams on this subject ....lmao

[@shogun666able]

Have you got nothing else better to do, like dig the garden or something useful as your beginning to bring a professional game down to a car boot sale. At a guess when they get to you and cannot solder you should show them the door. Guess the next will be the use of toilet paper correctly.

[@tomkatgastraining]

You don’t seem to have anything better to do but make unnecessary comments on KZbin videos. Remember I make my videos for trainees who have never soldered before so please go and make your smart arsed comments on someone else’s videos

[@user-yw6qb9tt7t]

Toilet paper use is a much more involved subject than people give it credit. I won't get onto what toilet paper you should choose on your particular budget as that is another big subject. Keep making great videos Derek. A trainee's lifeline ! 😀
