This is a hands-on welding course and is designed around the student doing the actual welding during 90% of the class. The instructor will train each student in the proper techniques and procedure for placing beads. Lectures are stand up; handouts and pocket guides are provided along the way, as needed.

Welders Training - Pipe welder qualification and certification as per ASME

REGISTER

OBJECTIVES

The trainee’s entrant to acquire the basic skills / practice of Shielded Metal Arc Welding. The course is carefully designed to offer the necessary theoretical and practical exposure in Shielded Metal Arc Welding Process. The lessons are planned in a sequential step-by-step approach to enable the participants to easily train from beginner level to a competent pipeline welder
