Fabrication ProcessJoining two or more elements to make

a single part is termed as fabrication process.

Fairly large numbers of industrial components are made by fabrication process .

Examples: Aircraft ,Shipbuilding, Bridges, Sheet metal parts etc.

Welding is a joining process that uses heat, pressure, and/or chemicals to fuse two materials together permanently. Welding covers a temp range of 1500º F - 3000º F (800ºC - 1635ºC).

Plastic Welding The pieces are heated to a plastic state and

then forced together by external pressure.

Carbon Arc WeldingIn carbon arc welding heat is produced with an arc between a carbon electrode and work, normally no shielding gas is used.

Carbon arc welding process can be used as an all position welding process.

MIG WeldingIn mig welding process a consumable wire of 0.8 to 2.4 mm dia is wounded in spool form is feed at a preset speed through a welding torch where it is provided the electrical connection and the shelding gas.

TIG WELDINGTig welding is a process in which the source of heat is an arc formed between a non consumable tungsten electrode and the work piece, shielding gas argon is supplied continuously during welding

Submerged Arc WeldingSubmerged arc welding is the process in which continuous copper coated spooled wire is used with loose granulated powder ahead of the arc , so to protect the molten pool from atmospheric gases.
