Explosive Welding - Advantages and Disadvantages:

Explosive Welding Advantages:

(i) Ease of the process.
(ii) Extremely big surface can be bonded.
(iii) Welds can be created on heat-treated metals with no affecting their microstructures.
(iv) This foils can be bonded to heavier plates.
(v) Broad range of thicknesses can be explosively clad jointly.
(vi) Explosive bonds have a solid condition joint that is free from warmth affected zone.
(vii) Good explosive bonds typically contain strength equal to or greater than that of the weaker of the two metals joined.
(viii) Lack of porosity, phase changes and structural changes communicate improved mechanical properties to the joints.

Explosive welding Disadvantages:

(i) In industrial areas the use of explosives will be harshly limited by the noise and earth vibrations caused by explosion.
(ii) The rules relating to the storage of explosives and the difficulty of preventing them from falling into unauthorized hands can well prove to be the major obstruction to the use of explosive welding.
(iii) A limitation to explosive cladding is concerned with the fragility of the alloys. Metals to be bonded by this procedure must possess some ductility and some crash resistance. Metals harder than about 50 RC are tremendously hard to weld.
(iv) Metal thicknesses bigger than 62 mm of every alloy cannot be joined simply and need high explosive loads.
(v) Resources such as beryllium, tungsten, boron, glass and ceramics are not usually processed by explosive welding.
