Metal fumesHealth riskCancerThe international agency for cancer research (IARC) has classified welding fumes as definitive carcinogens. The aim of the present study was to assess health risk due to exposure to welding fumes in different welding types. In this study, exposure to fumes of iron (...
Welding is a process of joining two or more pieces of metal by melting and fusing them together. Welding beads are the lines or seams of metal that form along the joint as a result of welding. They are important indicators of the quality and strength of the weld, as well as the skill ...
In addition, the risk of non-carcinogenicity due to exposure to Ni and Fe in all three types of welding was more than standard level (HQ>1). The results indicated that the welders are at health risk due to exposure to metal fumes. Preventive exposure control measures such as local ...
The 22 Types of Welding Jobs 1. Tack Welder Image credit: Creative Commons CC0, pxfuel A tack weld is a small weld that is meant to hold items in place and maintain their proper positioning so that the main weld can be performed. Rather than trying to hold heavy pieces of metal in pl...
