Spot welding is the most basic and generally, the most economical of all resistance welding techniques and lends itself to many forms of mechanization and automation. It can be used where speed is not a critical factor, double-thick lapped joints are acceptable, and normal electrode maintenance time is tolerated.

Spot Welder FEATURES

Min. Max.

WELD DESCRIPTION

Single Row Spot

Single Row Spot- Welds for heavier gauges were double the thickness is acceptable

Double Row Spot

Double Row Spot- Welds for heavier gauges were double the thickness is acceptable and weld will not be recoiled

The top 3 types of spot welders are listed below:

This machine is a manually traversed air operated welding unit consisting of two spot welding guns and transformer. Air operated strip clamps and optional strip centering devices are illustrated. Electrode arrangements available permit series welds for thin gauges of strip, or indirect welds, suitable for steel strip up to approximately .125″ (3.2 mm) in widths of 15″ to 80″ (380 to 2030 mm).

The machine above shows a more automated machine which is offered in various strip capacities to .250″ (6.3 mm). Different models make two or four spots simultaneously in an overlap of about 8″ (203 mm). Welding head is hydraulically traversed and controls provide for fully automatic indexing across the strip. Strip clamps, support rolls and centering devices are provided.

Taylor-Winfield’s heavy-duty, power traversed spot welder has found wide acceptance in heavy gauge processing lines. The welding gun is moved by a manually controlled motorized drive. The operator thus controls spot spacing and the quality of spots.
