the effect of santa j and power flex welding electrodes on the mechanical properties of arc welded joints using low medium and high carbon steels By mustapha Bello Welder& 39 s Handbook 3rd EditionWelded pipe with filler material can be used in the manufacturing of long radius bends and elbow Welded pipes are cheaper with compared to the seamless pipe and also Weak due to the weld There are different welding methods used to weld the pipe ERW Electric Resistance Welding EFW Electric Fusion Welding But they don’t include pipe welding positions So we are going to take a look at these now Pipe Welding Positions Pipes are used in so many different situations so the exact welding position you use will be figured out on a project by project basis Usually the position in pipe welding tends to be fixed However there are exceptions to 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 Welcome to this welding guide Here we will cover the various types of welding that as a beginner welder you are likely to encounter Whether you are thinking about welding as a career or just want to do welding as a hobby or for DIY welding jobs around the home weve got you covered Gullco International is a world‑renowned manufacturer of automated welding carriages welding tractors cutting carriages welding automation and accessories Welding Positions Pipe welding has four positions 1G the horizontal rolled position In this position the pipe is horizontal and it is being rolled so that you the welder are actually in a flat position relative to the pipe Oct 08 For in service pipe welding a butter pass is used in place of a root pass Buttering is a term that refers to adding weld material to build a part up A butter pass adds a layer to an in service pipe to help prevent burn through This builds up the pipe wall making it thicker so the operator can add more weld metal to it The most common welding procedure for pipe is stick welding SMAW But other methods like TIG and Oxy Acetylene welding are used as well There is a lot of room for employment in the pipe welding field It& 39 s a specialty field all of its own

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 Pipeline welding is important in industry The chief methods are used in the welding of pipelines for gas oil water etc There are several types of pipe joints Pipes may be joined by either fixed position welding or roll welding Pipe welding in fixed position and the lengths of pipes to be welded are placed on rollers for easy rotation Pipe welding certifications You can train in various different pipe welding techniques and earn certifications for each of the different pipe welding positions However as mentioned previously a 6G welding certification is really appealing to many welders and employers because of the high skill level which the technique requires 6G Pipe Welding Position The 6G pipe welding position is often referred to as the 6G inclined welding position thanks to its sloping 45 degree angle This can be 45 degrees from either the vertical the Y axis or the horizontal the X axis Not to mention that it is also fixed so it won’t roll for you as you weld A Guide to Automated Welding In the right applications automated welding can substantially improve the quality productivity and profitability of manufacturing operations Despite this potential the welding process is often overlooked or ignored while manufacturers […] Read More January 7 The Importance of Good Weld PreparationGuide for Welding Mild Steel Pipe American Welding Society / 20 Jul / 49 pages ANSI/ASME B31 1 Power Piping American Society of Mechanical Engineers / 29 Jun / pages An article on Pipe Welding was published in the Issue No 11 of Practical Welding Letter for July 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 Related reading The 4 Main Welding Positions You Should Know – Complete Guide Pipe Welding Techniques Since we have just looked at the pipe welding positions that you need to be aware of for your SMAW 6G certification and one you didn’t shhh we shall move onto the techniques you will need Open Root Pipe Welding TechniqueThere 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

Welding began the first week of October and only a few tie ins remained by Christmas “The pipeline industry is based on precision welds and lots of footage ” says Coker welding foreman Welded Construction L P of Perrysburgh Ohio “How fast we weld directly relates to how many feet of pipe the contractor can put in the ground PIPE POSITIONS There are also four types of pipe to pipe fillet weld technique These are Followings 1F or Flat Position Pipe with its axis inclined at 45 deg to horizontal and rotated during welding so that the weld metal is deposited from above and at the point of deposition the axis of the weld is horizontal and the throat vertical as shown in below figure TIG welding is a skill that needs to be developed over time with a piece of metal in front of you and with a welding torch in your hands TIG welding requires patience and practice The R Tech Tig AC/DC TIG Welder used in this guide 1 WHAT IS TIG WELDING TIG Welding can be used to weld aluminium copper titanium etc… and even two The most popular method for welding pipe is the shielded metal arc process however gas shielded arc methods have made big inroads as a result of new advances in welding technology Students enrolled in the Welding Technology Level 2 Program will learn the techniques necessary to certify to the following codes AWSD1 1 API and ASME Aug 18 TIG welding TIG welding uses tungsten inert gas and is a more expert form of welding Instead of a wire electrode like in MIG welding TIG welding uses a tungsten electrode to create the arc This type of welding can be used for metals such as alloys 7 It is important for pipefitters and pipe welders to follow the right welding procedure Be alert that welding sparks and hot materials from welding can easily go through small cracks and openings to adjacent areas Watch for fire and keep a fire extinguisher nearby Be aware that welding on a ceiling floor bulkhead or partition can cause fire on the hidden side Do not cut or weld on tire rims or wheels Tires can explode if heat Depending on the type of welding it can either be a nondestructive test NDT or a destructive test Welding Certification Positions Welding certifications come in many different positions depending on the type of structure that will be welded In most cases it is broken down between structural and pipe welding Open orbital welding heads of the carriage type travel around the tubes or pipes on suitable rails or tracks which can be mounted on any tube OD from 32 mm 1 3″ upwards The wall thickness of such tubes and pipes always requires multi pass welding
