Welding should be done by whom?

Welding should be performed by a certified welder due to the critical importance of safety and quality in welding processes. A certified welder has undergone formal training and has proven their proficiency in welding techniques, including understanding materials, welding methods, and safety protocols. This certification ensures that the welder adheres to industry standards and regulations, which are essential for maintaining structural integrity and safety in welded joints.

In contrast, an apprentice welder is still in the training phase and may not have the requisite experience or knowledge to perform welding independently. An unlicensed welder lacks the formal recognition of their skills and could pose risks to both safety and the quality of work. Similarly, a junior welder may not have sufficient experience or qualifications required for high-stakes welding tasks. Hence, the role of a certified welder is paramount in ensuring adherence to safety protocols and achieving high-quality welding results.
