Argon welding
Argon welding use the argon as a protective gas welding technique,so also called argon gas welding. That is, around the arc of the argon gas through the air isolated from the welding area,to prevent oxidation of the weld zone. Argon welding technique is based on the general principle of arc weldi...Read more -

Characteristics of medium carbon steel welding
Medium carbon steel generally refers to the carbon content of about 0.25 to 0.60% carbon steel. Manual arc welding of carbon steel casting and welding of the main features as follows: (1) Base metal near the weld area prone to low plasticity of hardened tissue. The higher the carbon content, plat...Read more
