Tig Welding; Tig Welding Procedures - Stel TIG μP 261H 1f Manual De Instrucciones

TIG µP 261H - 263H
TECHNICAL DESCRIPTION
stopping at the sides of the seam so as to avoid the accumulation of weld material
in the centre of the weld.
- Removing slag:
For coated electrodes, it is necessary to remove the slag after each pass. The slag
is removed with a small hammer or, in the case of brittle slag, with a wire brush.
To make the different types of joint correctly in the various positions, it is
necessary to practice under the guidance of an expert.
7.0– TIG WELDING
7.1- PROCEDURES AND TECHNICAL DATA FOR TIG WELDING
INTRODUCTION:
- Gas Tungsten Arc Welding (GTAW) is the definition of the welding process in
which the arc, during work, is maintained by means of an infusible metal electrode
(usually tungsten). The arc area (electrode and weld pool) is protected against
atmospheric contamination by means of an inert gas such as argon or helium,
which flows continuously through special ducts connected to the torch.
For the sake of simplicity and uniformity, all references to the process in this
manual are made with the term TIG (Tungsten Inert Gas).
- This process may be used for making clean and precise welds on any type of
metal, respecting its physical and chemical composition.
Thanks to this characteristic, TIG welding is the only method suitable for joining
certain metals.
- Due to the characteristics of the TIG process, the design of the welding machine
must satisfy specific requirements. TIG welding machines are designed and built
with these provisions. If they are installed, used and maintained correctly, they can
give long and satisfactory service, making correct, clean welds.
