Techspan-Tacking-Plastic-Welding

Tacking:
Welding of plastics components relies on a number of factors -
Surface Preparation
Good joint interfaces
Plastics Identification / Correct welding rod selection
"V" Grooving, using the rotary burr
Tacking
Correct welding temperatures
Welding technique

A Rotary Burr is used to provide a "V" groove along the weld line.

Tacking of plastics components prior to welding, helps the welder to achieve two things -
1. Good joint interfaces and
2. Alignment of the plastic components

The "Tacking Nozzle" can be used to ensure close joint interfaces and alignment of broken parts.  Unlike metal welding, where tacking is carried out at the ends of the welding area, Plastic Welding requires "Tacking" to be carried out where ever you intend to place welding rod. So if you have a crack of 100mm in length, you must "Tack" along the entire length (100mm) of the weld area. The "Tacking Nozzle" is an easy 'push-fit' onto the Techspan welding tool. It heats up to the corresponding temperature set on the welding tool, then simply run the tip of the tacking nozzle along the welding area. You will notice this will provide a slight "swagging" together of the two materials - closing up any gaps in the weld area.  If you notice any "un-tacked" areas, simply run the tacking nozzle over the weld line again, until there are no visible gaps between the mating surfaces.
