A Review on Under Water Welding Process - IJIET.
Welding is the process of joining two similar metals and it is applicable in most of the field like construction of bridges, huge buildings, railways, roadways, automotive and aircraft construction, pipe lines, tanks and vessels, machinery parts. This article deals with the classification of welding methods, depending on the state of the material during welding: plastic or pressure welding.
Research on different energy directing surfaces for ultrasonic welding of advanced thermoplastic composites was performed. Special attention was paid to the influence of the orientation of the energy directors with respect to the load direction and to multiple energy directors’ configurations. Keywords: Thermoplastic composites, processing techniques, ultrasonic welding, energy directors.
Paper presented at the I Mech E seminar, 'The Joining of Plastics and Polymer Composite Materials', held on 24 October 2002 at TWI and published in The Joining of Plastics and Polymer Composite Materials. Introduction. The majority of everyday products contain a joint of some description, with even small items such as mobile phones incorporating over 100 joints. Polymers and composites can be.
In Handbook of Plastics Joining (Second Edition), 2009. 6.2 Advantages and Disadvantages. Hot gas welding can be used to weld practically any shape or size of component, and the equipment has probably the lowest cost of all the plastic welding techniques. Hot gas torches are very light and easy to use in awkward positions, and are ideally suited for field repairs where the component is too.
Plastic Welding or Pressure Welding: When the metal piece acquires plastic state on heating, external pressure is applied. In this process, externally applied forces play an important role in the bonding operation. “A group of welding processes which produces coalescence at temperatures essentially below the melting point of the base materials being joined without the addition of a filler.
This paper presents the optimum ultrasound welding parameters of copper sheets usingstatic analysis methods results and microscopic structural analysis. Also it get the conclusion thatweld formation it’s produced after the plastic deformation process of metals because the action ofultrasonic energy in the joint area Topics: Ultrasounds, Optimum tehnology, Copper, Materials of engineering and.
Numerous welding methods have been evolved for the joining of plastic materials. This paper presents development one of the hot air plastic welding where the hot air is used to fuse or melt a filler thermoplastic rod and simultaneously heat the surfaces to be joined. In case of hot-gas welding the parameters of welding such as welding.
