1. Principle of Explosive Bonding
Explosive Welding Bimetallic Strip for Aluminum and Steel Welding
Metal dynamic cladding technology uses high energy from explosive detonation to produce a metallurgical weld between metal plates. It can produce high voltage pulse energy, pushing cladder collide with backer at a specific velocity and impact angle. That process produces much bigger stress than the yield strength of metal material. All these happen at instantaneous moment and simultaneously infinitesimal adjacent area of collision point of limited loading stress of materials, realizing wavelike metallurgical weld of two materials.
Explosive bonding is free from materials shape, thickness and areas. It realizes metallurgical connection between dissimilar metals. Metallurgical bonding ensures no distributed transverse crack. It makes dissimilar metal combinations possible which are conventional impossible to weld while original metal properties maintain and joint/ bond stronger than the weakest material. And it saves rare metals and cost effectively, thin layer of expensive material cladded on a thicker layer of cheap material.
 
2. Advantages of Aluminum Steel Cladding Transition Joint for shipbuilding
1) Background of shipbuilding
Light weight and high rigidity materials, like aluminum alloy, are widely used to build the superstructure of ships, rail vehicles and heavy trucks.
The major shortcomings of rivets and bolts are that they require holes to be drilled, need special insulators and require regular assembly inspection. Any removal of material, such as drilling holes, also weakens the metal.
 
2) Phohom's Advantages
Phohom's aluminum steel cladding transition joint is commonly used to make a welded and maintenance free connection between alloyed aluminum components and steel structures in the shipbuilding, railway and automotive industry. 
Aluminum steel cladding transition joints is an indisputably better option because they eliminate crevices and have shown to limit crevice corrosion. Aluminum steel cladding transition joints require no extra hardware, which allows engineers to stream-line their designs and shave off extra weight.
