Description:
CHW-50C3
is a coppered
solid wire for welding with Ar+CO2 gas mixtures. It shows a very good
welding performance especially in the range of lower current in case spark
is much lower than CHW-50C6SM (ER70S-6). Molten steel flows smoothly and
weld seam has a high crack-resistance. It is suitable for butt or fillet
structures made of mild steel and 500Mpa high tensile steel, in particular
for high speed welding sheet-steel.
