What welding with argon arc soldering
Stainless steel welding wire or CO2 gas shielded welding wire, spot welding 70-80A, full welding 110-120A, wire speed 0.2m/S
Why so many laymen, join in the fun?If not required, use two wire, ER50-6Then we can use submerged arc welding wire.
The pig insurance or by WE777 cast iron electrode used cast iron welding rod, usually without argon arc welding welding, argon arc welding of cast iron is easy to crack, if the structure can only allow the use of argon arc welding, argon arc welding of cast iron can be used for WE777, WE77.WE777 has a special coating, the welding process can produce the impulse like soft arc, thermal effects on various types of iron base material is very small, the special pulse arc can remove impurities of cast iron surface, even for long-term oil and oil cast iron welding has good permeability without blowhole or mixed, and the hardness of heat affected zone will become very high, forming weld by cold welding process has excellent crack resistance, can deal with all kinds of bad parent material environment.Application of WE777 special cast iron welding rodSuitable for the full range of cold welding welding, welding cast iron base material can almost all, and it is easy to achieve cast iron and carbon steel dissimilar metal welding, such as solving matrix fracture, crack, wear, hole filling defects after welding can be machined, many applications in the engine casing, cylinder head, casting machine, gear base the tooth of iron castings.Technical parameters of WE777 special cast iron welding rodThe tensile strength of more than or equal to 70000 PSI (more than 482 n / mm2)Yield strength: General 62000 (more than 427 n / mm2)Hardness (HB): 185HBWith the parent material color: similar power options: AC and DC dual-use, DC DC reverse connection
