There are three types of underwater welding: dry method, wet method and partial dry method.
Dry welding
This is a method in which a large air chamber is used to cover the weldment, and the welder ...
Welding electrodes are metal wires with baked on chemical coatings. The rod is used to sustain the welding arc and to provide the filler metal required for the joint to be welded. The coating prote...
Introduction
Proper storage of welding consumables is often overlooked — but it directly affects welding quality, safety, and cost.
Incorrect storage can lead to:
Moisture absorption
