Product Overview
Welding wire rod is a specialty wire rod that is drawn into gas metal arc, tungsten inert gas and submerged arc welding wires. Jingye supplies ER70S-6 to AWS A5.18, EM12K to AWS A5.17, and SWRY11 and SWRY11Cr to JIS G3503, with Chinese equivalents under GB/T 3429 such as H08A and H08Mn2Si.
Chemistry is tightly controlled with low sulphur and phosphorus and appropriate silicon and manganese levels, so that the drawn wire delivers a stable arc, low spatter and sound weld metal properties.

Delivery, Testing and Quality
Wire rod is produced on high-speed wire rod mills and released with a mill test certificate, with chemistry, decarburisation and surface quality controlled for downstream drawing, cold heading and welding. Products are manufactured under ISO 9001 and ISO 14001.
Frequently Asked Questions
- What does ER70S-6 mean?
ER denotes electrode rod, 70 indicates a minimum tensile strength of 70 000 psi, S denotes solid wire, and 6 identifies the chemical composition variant. It is the most widely used gas metal arc welding wire.
- What is the difference between ER70S-6 and EM12K?
ER70S-6 is used mainly for gas shielded welding, while EM12K is a submerged arc welding wire with higher manganese for use with a flux.
- Do you supply the finished welding wire?
Jingye supplies the welding wire rod, which welding consumable manufacturers draw and copper-coat into finished wire.
