SP welder means Structural purpose welder.
The answer is "YES". ASME IX allows a welder qualified on base metal P(or S) number 1 to 11 to weld P1 to 11. Please refer to ASME IX QW-423. Hope this helps. Sun.
In my experiences with 110 machines I've found that for strength 1/16" is a good thickness. Argon/co2 seems to work better than coated wire for metals thicker than that 1/8" - 5/32". 1/4" is usually too thick to weld as the heat is pulled away from the weld area producing poor or no weld. Remember, this is a "short arc" process. The arc is not on long enough to melt thick material.
6010 is a high cellulose sodium based electrode, which can be used to weld carbon steel pipes.
No, I can't.
In order to weld pieces of 6mm steel you can use any type of welder. Depending on how strong and how pretty the weld needs to be will determine the type of welder you choose.
about 2mm mild steel max
can weld aluminium with a mig or tig welder
Yes because you may need to figure out where to weld by using math
SP welder means Structural purpose welder.
The type of welder is dependant on what you want to weld with the machine. Welding heavy steel will take a bigger machine than one that is used for light metal.
Tig, mig , or If you are as good as me stick welding will all work
arch welding is a more stable form of welding. it get hotter and creates a stronger bond
Weld
Yes, you can weld steel to steel. You can use steel welding rod.
yes
Yep, you can weld steel to stainless and you can weld stainless to steel. You can use steel or stainless welding rod in either case but the steel or steel welding rod will of course rust.
