There are four main pipe welding positions numbered 1 2 5 and 6 The 1G position isn’t used very often but it’s still important to recognize it This is pretty much just flat welding because the pipe will be lying on its side on the curved edge and can be rotated as you weld The 2G position is fixed PREFACE All 40 years of m y working lif e I spent on erection of diff erent process plants most of which were oil indus try projects in the country and abroad in Europe and North Africa weight per foot on the pipe making weight calculations simple You can also use pipe charts when they are available but when necessary calculate the weight of steel pipe by using the formula below If there are multiple pieces of the same size and type of pipe remember to multiply the weight of one piece by the total number of pieces There is a system of letters and numbers which acts as a code to indicate which joint type and position to use Fillet welds do exist with pipe welding but they’re very uncommon they’re indicated by the letter F Far more common are groove welds which you can identify with the letter G Explore our high quality Cutting and welding Carriages Collection such as Torch Runner Track Cutting Machine Rail Runner Welding Carriage Arc Runner Welding Carriage & much more!Mar 01 Just like structural welding positions pipe welding certifications come in two joint types F is for a fillet weld G is for a groove weld 1G Pipe Welding Certification Position The 1G pipe welding certification position is a pipe in the horizontal position and the pipe is rolled when welding This is basically welding in the flat position Spiral submerged arc welding SSAW steel pipe also called HSAW pipe welding line shape like a is using the same welding technology of Submerged Arc Welding with LSAW ferently SSAW pipe is spiral welded where the LSAW is longitudinally ufacturing process is rolling the steel strip to make the rolling direction have an angle with the direction of the pipe center This engineering drawing present weld type symbols and fillet weld symbols < br> The weld type symbol is typically placed above or below the center of the reference line depending on which side of the joint it& 39 s on The symbol is interpreted as a simplified cross section of the weld < br> " Fillet welding refers to the process of joining two pieces of metal together whether they be perpendicular Supports that Require Field Welding Pipe shoes and pipe guides are available in a variety of designs Slide plates may be included on the pipe shoes for smooth sliding Custom pipe shoes and anchors can be designed to meet your specific design requirements

6G Pipe Welding Techniques Positions & Procedures

6G Pipe Welding Techniques Positions & Procedures

For pipe welding jobs more often than not a 6G pipe test is given That means the pipe is placed on a 45 degree angle and it is fixed… it cant be rolled or moved until its done Welding in the 6g position tests your ability to reposition your body it tests if you can weld left handed and it tests being able to weld in all positions flat Jun 08 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 The Track Welding Carriage With Oscillator is a track welding carriage designed to produce butt and fillet welds with or without oscillation The carriage can work in PA flat PB horizontal vertical PC horizontal PD overhead horizontal vertical PE overhead PF vertical up and PG vertical down welding positions which is hard to determine a priori In [2] di erent welding techniques and their characteristics are described together with other useful information regarding welding i e di erent joint types Base material HAZ Fusion zone HAZ Base material Figure 2 1 2 Zones close to the weld Important areas of the weld are shown in Figure 2 1 2 The most common type of joint used for welding together pipe is a butt joint Very simply you take two pipes and put them together and now you have a butt joint to weld But if you are welding thicker walled pipe then you are going to bevel a V or U butt joint Singles only The purpose of the Welding Handbook for maritime welders is to provide guidance in modern welding and related processes and to provide the welder with a source of practical information on the right solution to specific onboard welding problems Experience gained from user contact and welding training of crewmembers showed thatThe Track Welding Carriage With Oscillator is a track welding carriage designed to produce butt and fillet welds with or without oscillation The carriage can work in PA flat PB horizontal vertical PC horizontal PD overhead horizontal vertical PE overhead PF vertical up and PG vertical down welding positions For example a carbon steel pipe can be identified with Grade A or B a stainless steel pipe with Grade TP or Grade TP a carbon steel fitting with Grade WPB etc Below you will find as an example 3 tables with chemical requirements for Flanges ASTM A Grade F FL FL Pipes ASTM A Grade TP TPL TPL
