Welding fabrication involves several operations which might have a significant ergonomic impact.
This article aimed at providing an overview on these typical activities, and the most confusion on terminology of Partly Mechanized and Fully Mechanized processes during identify the welding personnel as a WELDER or WELDING OPERATOR?
The role of welding personnel in welding processes:
Based on the level of automation, processes are defined by applicable industrial standards as:
– Manual processes, involving welders;
– Partly mechanized (or semiautomatic) processes, involving welders;
– Fully mechanized (or automatic) processes, involving welding operators;
– Automatic and/or robotized processes, involving welding programmers, operators.
Depending on the industrial needs, some processes may be used with different levels of automation.
Refer to EN ISO 9606-1 (manual or partly mechanized welding processes) and EN ISO 14732 (mechanized and automatic welding) definition:
Welder: One person who holds and manipulates the electrode holder, welding torch or blowpipe by hand.
Welding operator: One who operates machine or automatic welding equipment
According to EN ISO There are Two (2) Certification formats for Welder / Operator respectively
Refer to ASME IX (Two (2) Certification formats for Welder / Operator respectively) definition:
Welder: One who performs manual or semiautomatic welding.
Welding operator: One who operates machine or automatic welding equipment
Refer to AWS D1.1 (Only one (1) Certification format for Welder / Operator) definition:
Welder: One who performs a manual or semiautomatic welding operation.
Welding operator: One who operates adaptive control, automatic, mechanized, or robotic welding equipment.
