end of the pipe. Welding the Root Pass Before beginning to weld the pipe, the procedure should be checked to assure that the correct electrode is being used. This includes the diameter and the classification of the electrode. The welding con-sumable should be selected to correctly match (or overmatch) the strength of the pipe.
ASTM Welding Procedures A36 to A930 - Weld Reality
IF YOU AR E WELDING TUBES OR PIPES MAKE SURE YOU VISIT THE ASTM PIPE WELDING SECTION If welding a carbon or low alloy steels and you don't know what the composition is or what the weld consumable should be, give consideration to the following. If the metal is thicker than 1/4 - 6 mm, preheat to 150F.

Characterization of the Welded-Joint of High-Strength High
The welded joint of a S890QL grade steel pipes containing 1.2% Ni have been prepared to characterize the use performance under high cycle fatigue test. It has been found that the fatigue strength of the welded joint is 290MPa with a fatigue life of more than 10 million cycles, and the obtained Basquin equation is σa=488*(2N)-0.02758 . It is found that the steel exhibits the whole bainite
ASSEMBLY PROCESSES Welding FUNDAMENTALS OF WELDING
• Laser Beam welding – A high-power laser beam as the source of heat to produce a fusion weld without a filler material – Due to the high density energy on a small focused area, narrow and deep penetration capability – Pulsed beam for spot-weld thin samples – Continuous beam for deep weld and thick sample – e.g.: Gillette Sensor
Effects of Post Weld Heat Treatment (PWHT) Temperature on
P91 is a typical high-Cr ferritic heat-resistant steel and is applied particularly to large diameter thick-walled pipes such as the main steam pipes in thermal power plants. The welded joints of Gr. P91 steel are generally subjected to post weld heat treatment (hereinafter referred to as "PWHT") to reduce residual stress and
Differences Bewteen Seamless Steel Pipe and Welded Steel Pipe
Seamless steel pipe has better pressure capacity, strength is higher than ERW welded steel pipe. So it is widely applied in high pressure equipment, and thermal, boiler industries. Generally the welding seam of the welded steel pipe is the weak point, the quality affect overall performance.
Preheating, Interpass and Post-Weld Heat Treatment
PREHEATING, INTERPASS AND POST-WELD HEAT TREATMENT REQUIREMENTS FOR WELDING LOW ALLOY STEELS 1.0 INTRODUCTION 1.1 Issue: 1-5 In fusion welding processes (see 2.1), the reason often given to explain the need for preheating, controlling the interpass temperature (in multipass welds), and post-weld heat treatment (PWHT) is to reduce the risk of cold

A plug weld is a weld made in a circu-lar hole in one member of a joint fus-ing that member to another member. A slot weld is similar to a plug weld except that the hole
Heat Affected Zone and Weld Metal Properties in Welding of
Heat Affected Zone and Weld Metal Properties in Welding of Steels . There are many factors which control the properties of the weld metal and heat affected zone (HAZ) while welding of carbon (C) and low alloy steels. The weld metal and HAZ are frequently referred as steel weldments.
