Thread: Welding Pictorial

Tweet

With all due respect, All these pictures are good for only one thing and that is basic set up of heat and speed. As far as welding the ones displayed are not good quality welds for real world application. Those displayed can be helpful, but they are only seal welds. bend them into the face and they will all break. Less then 100% penetration in prepped condition is already cracked from the inside. i know I sound critical but after welding and teaching welding with over 40 ASME certs in nuclear, petroleum, power generation it kinda bothers me some of the automotive/welding instruction is so poor. I see all the time people showing tig welds by dipping on metal defined as a row of nickels as being perfect, when in reality they are junk welds. SS and aluminum are far the easiest to weld, SS exhaust should always be purged tig welded where 100% pentration is accomplished and the inside looks exactly like the outside. It is easy. I have to much respect for hot rodders to not say something. I hope I don't offend anyone, that is not my intent. But I see a lot of cars build that aren't even safe to drive down the road.

Which re-affirms my statement above to the importance of schooling..

I certainly know what your saying but have you ever seen the factory welds on a car frame?? I mean really...I have seen the factory welds on a '67 Corvette, 72 SS Chevelle, 65 Nova and 65 mustang a 12 year old girl could weld better, just check out that front crossmember on a muscle car, it might amaze you, you will think those rods welds look like pro's. I even went as far as arguing on the Nova that someone had replaced the crossmember that couldn't weld as the wire was still attached in about 3 places and cut off the gun, I was surprised when the builder was correct they are just that bad from GM.
I myself would love a video on tubing, never can learn to much!
