While deposition rate is often used to evaluate welding productivity, one must also consider the better factors that influence arc on-time. Preheat time, bead shape, slag removal and defect repair are often overlooked when describing efficiency, but are critical to the overall project cost. The result of diffusible hydrogen, selecting alloy systems and picking out welded procedures all play a crucial role in preserving high quality and persistence in offshore weldments.

Welders and welding engineers face distinct challenges in an era of increased overview by governmental regulations, customer's representatives and agency distinction societies. This involves that the design engineering, manufacturing and construction organizations re-think the margin of protection in their welding operations. To control costs, designs incorporating higher strength materials are typical, as are higher productivity PVC Welding procedures. The two the higher strength mining harvests and higher productivity types of procedures raise the risk of slowed cracking. Hydrogen-related cracking may be a function of the number of hydrogen, the susceptibility of the microstructure and the remainder stresses on the metal. Increased output in welding almost always results in thicker specific weld passes and more weld passes per hour (for a fraction of the time between passes). The result is much larger diffusion distances, shorter durations for hydrogen to get away and an increased risk of hydrogen related damage. These factors, specially when merged with the microstructures of higher-strength steels, require a new look at hydrogen control in every part of welding.
