Simple Edge Preparation: TIG welding typically requires minimal edge preparation, saving time and effort in the
welding preparation process.
Automation is Easy: TIG welding can be easily automated, allowing for increased productivity and consistency
in welding operations.
All-Position Welding: TIG welding can be performed in various positions, including flat, horizontal, vertical, and
overhead, providing flexibility in welding applications.

Produces Desirable Root Penetration in Pipe Welding: TIG welding is favoured for pipe welding due to its
ability to produce desirable root penetration, ensuring strong and reliable weld joints.

Slotting Machine
Introduction to slotting machine:
A machine tool with a vertically reciprocating single point cutting tool used for performing internal operations or
shaping the side in metal machining. A slotting machine, also known as a slotter, is a specialized machine tool
used for machining slots, keyways, grooves, and other internal or external features in workpieces. It operates by
vertically reciprocating a single-point cutting
tool called a slotting tool or ram against the workpiece to remove material and create desired slots or features.
Slotting machines are commonly used in manufacturing, metalworking, and toolmaking industries for producing
components with precise slots and keyways.
Principal of slotting machine:
The principle of operation of a slotting machine involves the vertical reciprocating motion of a single-point cutting
tool, known as the slotting tool or ram,
against a stationary workpiece to create slots, keyways, grooves, or other internal or external features.

Parts of slotting machine:
1 Base: The base is the foundation of the slotting machine, providing support and stability to all other components.
It is usually made of cast iron or welded steel and provides a rigid platform for the entire machine.
2 Column: The column is a vertical structure mounted on the base and supports the ram and other moving
components of the slotting machine. It may contain guideways or tracks to guide the vertical movement of the
ram.
3 Ram: The ram is a vertical component that reciprocates up and down along the column. It supports the slotting
tool and provides the means for cutting slots, keyways, or grooves in the workpiece. The ram is driven by a
mechanism that controls its vertical movement.
