Spot Welding Electrode

Spot welding tip (spot welding electrode) is for electronic spot welding machine, used for welding enamelled cable, metal naked cable; as well as cutting cable.

Material: tungsten or molybdenum

Shapes and Features of Spot Welding Electrode’s Tip

Welding tip types

The welding tips are various for welding different types of enamelled cable or metal wire. According to material and tip structure, the welding electrode can be divided into 6 types:

V type, Va type: material molybdenum, ohmic contact type

Vb type, 2D type: material tungsten, ohmic contact type

U type: tip connect type, tungsten material

P type: tip discontiguous parallel type, material tungsten or molybdenum

 

Standard Electrode Tips:

Pointed —Tapered From The Full-Diameter Electrode Shank To Required Size And With A Flat Surface, Holds Its Shape Well, But Is Difficult To Dress In The Machine Unless A Dressing Tool Of The Exact Taper Is Provided.
Flat — Employs The Full Shank Or Stock Size At The Welding Surface.
Dome — Used For Less Precise Work Where Easy Dressing Is Of Advantage. The Dome Shape Provides A Greater Approach To The Flat Surface Of The Work.
Offset — Is Used To Make A Spot Weld Closer To A Vertical Wall Than Is Possible With A Straight Tip. The Offset Of The Tip Should Be As Slight As Possible, As The Electrode Force Or The Compression Load At The Center Line Of The Electrode Axis Will Tend To Cause Bending Of The Tip. Since The Tendency Of The Electrode Is To Skid Or Deflect As The Offset Distance From The Center Of The Electrode Axis Increases, Offset Tips Should Not Be Used Except When Required.
Radius — Is Used For The Welding Of Aluminum And For Many Other Precise Applications Because Of The Superior Results To Be Obtained. The Spherical Surface Is Easier To Clean Without Removing From The Machine, Will Withstand Higher Pressures With Less Deformation And Is More Readily Aligned In The Holders.
