WHAT IS GD&T , EXPLAIN WELDING TYPES AND ITS FEATURES

Question

Accepted Answer

GD&T is a system for defining and communicating engineering tolerances. Welding types include MIG, TIG, and Stick, each with unique features.

GD&T stands for Geometric Dimensioning and Tolerancing, and is used to specify the allowable variation in form and size of features on a part.
MIG welding uses a wire electrode and shielding gas to join two pieces of metal together, and is commonly used in automotive and construction industries.
TIG welding uses a tungsten electrode and filler metal to create a strong, precise weld, and is often used in aerospace and medical industries.
Stick welding, also known as Shielded Metal Arc Welding, uses a consumable electrode coated in flux to create a strong bond between two pieces of metal.
Welding features include joint type, weld size, and weld position, and are specified using symbols on engineering drawings.
