ANALYSIS OF LASER WELDING PROCEDURE

ABSTRACT

Through this project, Lazer welding process has efficiently been used for joining of two stainless plates. The sizes in the metal discs are 50mmX40mmX2mm each. The distribution with the temperature

discipline in laser beam welding using stainless steel bedding were simulated by ANSYS.

The heat properties which were used for energy

simulation will be assumed being varying with temperature, curves of which are shown in the project. Journeying heat origin model of ANSYS was used intended for simulation purpose. Thermal simulation shows the temperature circulation at several position in the sheets for different time instants. The temperature distribution mainly depends on the real estate of the materials i. electronic. thermal

conductivity, specific temperature and the density of the material. These houses vary because non geradlinig function of temperature.

From this project, lazer welding of stainless steel was studied by different beliefs of heat debordement and welding speed results of which has been demonstrated in the realization part of the project.

INTRODUCTION

Welding is a fabrication or perhaps sculptural process that brings together materials, generally metals or perhaps thermoplastics, by causing coalescence. This is often done by melting the job pieces and adding a filler materials to form a pool of molten material (the weld pool) that lowers to become a good joint, with pressure at times used in

association with warmth, or independently, to produce the weld.

Different types of energy sources can be used for welding, including a gas flame, the arc, a laser, an electron light, friction, and ultrasound. Although often a great industrial process, welding could possibly be performed in numerous different conditions, including wide open air, under water in addition to outer space. Welded is a probably hazardous undertaking and precautions are required to prevent burns, electric power shock, vision damage, breathing of dangerous gases and fumes, and exposure to powerful ultraviolet light.

LASER WELDING

Laser Beam Welding (LBW) is known as a modern welding process utilized to join multiple pieces of identical and dissimilar metal through the use of a laser beam. Laser welded is based on the interaction of laser mild with matter. In general, lazer is focused within the material surface area and is somewhat absorbed. The absorbed energy is

moved into bulk material simply by conduction. The laser strength absorbed by the material begins to heat and melts the fabric. The burning material is going to solidify quickly to form a weld.

Laser welded is a high energy beam process that continually expand in modern industries and fresh applications due to the many positive aspects like profound weld transmission and minimizing heat inputs. The switch by the companies to systemize the

welding processes has additionally caused to the expansion in using excessive technology like the use of laser and pcs to improve the item quality through more accurate power over welding

procedures.

Depending upon resource, LBW is definitely classified in to mainly 2 categories: Sturdy State Laser beam...
