ABSTRACT

Ultrasonic metal welding is a solid state welding process, and here ultrasonic vibrating motion is used to join two materials. The two work pieces are held in between the anvil and sonotrode. The work piece on the anvil is hold stationary while the other part is moved to and fro due to the vibrating effect of the sonotrode. This movement the oxide disperses layer in between them and atoms of the work pieces are diffused from one part to another. When vibration is stopped a pure metallurgical bond is obtained.

INTRODUCTION
This paper is an update of a previous paper authored by Mr. Humphry Udall, former
Director of Research and Development for Thermatool.
The welding of stainless steel tubes differs substantially from the welding of high quality
carbon steel tubes in a number of ways. The most significant difference is in the melting
point of the oxides that are formed on the faying edges during the welding process. The
oxides formed on carbon steel generally melt at a temperature lower than the melting
point of the steel. Since the oxi ....etc

Abstract :

The case study project is significant since mild steel is used in structure, case hardening, gears, free cutting steels, shafting, forging etc. Mild steel plates were tested for mechanical properties like hardness, tensile strength, yield point etc. Later on the plates were joined by submerged arc welding and the mechanical properties were estimated again. Also weld ability, harden ability, tensile test etc. were conducted for the same result. ....etc

stainless steels


What are stainless steels

Alloys of iron, chromium and other elements that resist corrosion in many environments
A minimum of 12% Cr is required for it to be a stainless steel

Ferritic stainless steels

Have a BCC ferrite microstructure
Low carbon contents (<0.2%)
Cr in the range 12-20%
They remain ferritic all the way up to melting point
Poor weldability
Extra low interstitial grades developed with improved weldability

Martensitic stain ....etc

Abstract
A significant percentage of the flux used in submerged are welding gets converted into very fine particles particles
termed as flux dust due to transportation and handling. If these very fine particles are not removed fromt he flux before
welding, it may results ....etc
