5.2 Higher automation, productivity and quality control<br />
In every country, there is a relentless fight to maintain orders by increasing the productivity and improving<br />
the quality and the working environment. One simple means is to change the arc welding process from<br />
MMA to MIG/MAG or FCAW, which has been the case for many years in Western Europe, the USA and Japan<br />
as illustrated in Figure 5.10.<br />

One will certainly see a faster conversion from MMA in the Asian countries (62 % in China) than the ones<br />
shown in Figure 5.10. The amount <strong>of</strong> deposited weld metal in China is about 1.1M tons (Figure 5.11) or<br />
more than Japan, USA and Europe deposited together. China consumes more than one third <strong>of</strong> the total for<br />
the world, which amounts to 2,923 million tons. China has much more submerged arc welding (13%) than<br />
Western Europe (5%) due to the higher amount <strong>of</strong> plate welding consumed in the construction and shipyard<br />
industries.<br />

Arc welding will remain the most important joining process and its use will continue growing quickly in Asia<br />
as forecast in Figure 5.11.<br />
