EV Group China&#8217;s technological regulations are adapted for the use of these materials in gas metal arc welding (GMAW), gas tungsten arc welding (GTAW), and plasma arc welding (PAW) processes.<\/p>\n<p>Industrial safety and occupational health issues during welding operations are outside the scope of this technical description. We recommend consulting current industry standards and safety regulations, as well as reviewing the reference data in annexes A5 and A10.<\/p>\n<p>For the convenience of EV Group China&#8217;s engineering and technical personnel, all physical quantities are presented in two measurement systems: metric (SI) and US customary. It is important to note that values in different systems are not interchangeable equivalents. AWS specifications with an &#8220;M&#8221; index are based exclusively on the metric system, while versions without a letter index are oriented towards US standards. In this technical documentation, SI units are provided in the corresponding columns or indicated in square brackets for clarity.<\/p>\n","protected":false},"featured_media":0,"template":"","meta":[],"wiki_category":[121],"class_list":["post-69855","wiki","type-wiki","status-publish","hentry","wiki_category-aws"],"_links":{"self":[{"href":"https:\/\/evgroupchina.com\/en\/wp-json\/wp\/v2\/wiki\/69855","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/evgroupchina.com\/en\/wp-json\/wp\/v2\/wiki"}],"about":[{"href":"https:\/\/evgroupchina.com\/en\/wp-json\/wp\/v2\/types\/wiki"}],"version-history":[{"count":0,"href":"https:\/\/evgroupchina.com\/en\/wp-json\/wp\/v2\/wiki\/69855\/revisions"}],"wp:attachment":[{"href":"https:\/\/evgroupchina.com\/en\/wp-json\/wp\/v2\/media?parent=69855"}],"wp:term":[{"taxonomy":"wiki_category","embeddable":true,"href":"https:\/\/evgroupchina.com\/en\/wp-json\/wp\/v2\/wiki_category?post=69855"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
