No! Green Pin® products are treated with well designed heat treatment, which results in a certain Minimum Break Load and other specific mechanical properties. These properties will be destroyed by the heat of welding. It even can initiate extreme hard spots and initial cracks, that will decrease the strength and fatigue life dramatically. An exception is made for Green Pin® GH and PAS products, as these need to be welded to a surface to function. For these items, please follow the instructions that are available at Green Pin® sales.
