EB3R AWS A5.23:2021 EB3R
EB3R as a special submerged arc welding wire is widely demanded in the petrochemical industry. However, the performance requirements for EB3R are very different in different countries and regions. According to the performance requirements of the reference standard “AWS A5.23-2021”, “the impact test should be satisfied: ≥54J/-20°C”. EB3R produced in accordance with this standard through the test results are : …… https://www.akweld.com/elementor-2850/
AKG TZ-7 AWS A5.1 E7016
AKG TZ-7, equivalent: AWS A5.1 E7016 electrode, mild steel electrode, used for one-sided welding of pipelines and double-sided moulding welding, the use of small current single-sided welding, arc stability is very good, can be welded to mild steel and 490MPa level of high-strength steel pipe butt joints, and can be achieved by one-sided welding and double-sided moulding. The electrode belongs to low hydrogen type, when welding the root channel of pipeline and general structure, because it can realise one-sided welding and two-sided forming, so it can save the clearing welding, so that the welding efficiency can be improved……
