A simple and reliable manual gas pressure welding procedure was developed to apply for joint of high-strength bar. The gas pressure welding was performed by using a steel hollow cylinder with inner concave fitting for bulge of weld and inserting the cylinder in weld zone just before pressing. As a result, it was cleared that the present manual gas pressure welding procedure is applicable to the joint of high strength bar graded SD490.
