Diferença entre ER70S-2、ER70S-3、ER70S-4、ER70S-6、ER70S-7

AWS A5.18 is the specification for carbon steel electrodes and rods for gas shielded arc welding like gas metal arc (GMAW), gas tungsten arc (GTAW) and plasma arc (PAW) welding, we all know class ER70S-2、ER70S-3、ER70S-4、ER70S-6、ER70S-7welding electrodes can be used for welding the carbon steel and the low alloy carbon steel with a strength less than 500Mpa, […]

Gás de protecção para a soldadura MIG em aço inoxidável

Due to the small thermal conductivity and large linear expansion coefficient, the welding of Austenitic stainless steel is easy to produce deformation, so the welding method with linear energy concentration should be selected as far as possible. MIG welding (Molten inert gas shielded welding) using a molten electrode, with external gas as arc medium, and protect […]
