ER70S‑6 conforms to AWS A5.18. The designation breaks down as follows:
ER – Electrode or filler rod
70 – Minimum tensile strength of the deposited weld metal: 70,000 psi (~490 MPa)
S – Solid wire

1. The priority principle of arc welding with electrodes
For the installation and welding of pipelines whose diameter is not too large (such as below 610mm) and the length of the pipeline is not...
TIG spot welding (also known as gas tungsten arc spot welding) is a specialized technique that uses a tungsten electrode to generate an arc that melts a localized area of overlapping metal sheets,...
During fusion welding, under the action of the welding heat source, the liquid metal part with a certain geometric shape formed on the weldment by the molten electrode metal and the partially molte...
Vertical welding with stick electrodes gives many welders trouble. The molten metal wants to drip downward, the puddle sags, and the bead ends up uneven. But vertical welding is not as hard as it...
Many welding problems that show up on the shop floor—poor bead appearance, porosity, cracking—are often traced back to one overlooked factor: how the consumables were stored before they ever rea...
