Stick Welding Process Intro
SMAW (Shielded Metal Arc Welding) is often called stick welding. It is one of the most popular welding processes used today. Its popularity is due to the versatility...
First, Welding cracks and pores are generated.
The moisture absorbed by the welding rod becomes gas under the action of the welding arc heat, which decomposes hydrogen, resulting in the formation ...
Welding material standards are an important basis for ensuring welding quality and safety. Different countries or regions have formulated corresponding standards according to their own industrial n...
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
6...
In multi-pass and multi-layer welding, temperature control between each bead and layer is crucial. This is the “interpass temperature” under discussion. Interpass temperature refers t...
Welding stress and distortion is the stress generated in welded components due to welding. It includes internal stresses generated during the welding process and changes in shape and size cause...
