Usually, not always but usually the HAZ is what gives after welding a part back together... This is if the weld was done 100% correctly and you have no defects in the weld.. this is a good video I think it should be used as an instructional aid in welding courses to show what happens to welded areas when put under stress.😁👍
There are questions, though. Who did the welding? What rod was used? Some of the welders in the USAF were amazing in their craft. It’s a great video, however, and very interesting
Anytime you weld something it makes the area around it slightly weaker. And stick welding these small items doesn't make an accurate assessment for this test. They should be tig welded.
Yes indeed. The weld will most likely also be weaker by the fact that the filler material from those sticks are most likely meant for ordinary mild steel welds. Tools often uses other alloys that's harder. With TIG, the parts can just be melted together and/or filler material from other broken tools can be used.
the onlt problem with welding hardened things like sockets, is you pretty much destroy the tempering, and need to re-harden and re-temper, and I honestly dont know how TIG would react to that. not entirely sure MIG would take to it either..
Even TIG is arc welding (since it uses an electric arc as the heat source) - but TIG would indeed be much better for this. Not just because of better precision, but also the fact that tools are often made of special steel alloys - which is hard to find sticks for. Add material from sticks meant for mild steel, will make the weld weaker. With tig it's possible to just melt the parts together and/or use material from other broken tools (which may be grinded into strips first) as filler material.
Видео очень жизненное. Сломался инструмент. Прихватил и работать дальше. Никто не будет корпеть над сваркой, теряя драгоценное время, которое стоит дороже самого инструмента.
