摘要：
In an automatic gas pressure welding system wherein a couple of steel members are butted, the butted section is subjected to heating in a pressed state, to thus cause the steel members to be subjected to pressure welding. The pressing and heating periods are controlled in conformity with the amount of contraction of the heated section of the steel members.
