Two major hazardous by-products of welding are ultraviolet rays and fumes. a True b False

## Step 1<br />The problem statement is a statement about the hazardous by-products of welding. We need to determine whether this statement is true or false.<br /><br />## Step 2<br />The statement says that the two major hazardous by-products of welding are ultraviolet rays and fumes. This is indeed true. <br /><br />## Step 3<br />During welding, the intense light and heat produced can generate harmful ultraviolet (UV) rays. These UV rays can cause severe burns and eye injuries, which can be painful and potentially damaging.<br /><br />## Step 4<br />In addition to UV rays, welding also produces fumes. These fumes are a mixture of gases and metal oxides that are produced when the metals being welded are heated. These fumes can be harmful when inhaled, leading to respiratory issues.
