Jun 07 The welding variables are similar to the other arc welding processes with several exceptions We choose the electrode type and flux as per the metal to weld The size of the electrode is directly proportional to the weld joint size and recommended current The number of passes/ bead sizes to be considered and decide the joint Groove Weld Size The joint penetration of a groove weld Click to Enlarge Sep 05 For an MMA weld on carbon steel plates the typical angles is 25 30 Deg for a V preparation 8 12 Deg for a U preparation 40 50 Deg for a single bevel preparation 10 20 Deg for a J preparation Note The value is only for reference the angle and groove type is depending on structure design type welding processes and cost saving Shanghai Huawei Welding & Cutting Machine Co Ltd was incorporated at which is the leading enterprise in welding & cutting equipment industry Our featured products are flame cutting machine CNC cutting machine welding tractor beveling machine electrode dryer and oven welds which have been removed shall be replaced if necessary to maintain alignment or to prevent closing of the root opening during root pass welding Fillet weld sizes as shown on the Welding Procedure Specification shall be used unless otherwise detailed on the engineering drawing Fillet welds shall be made so that theyThe quickest way to evaluate the best choice for your welding process Step 1 Select the process FCW Flux Cored Wire Step 2 Select your weld preparation Click on the closest one to your project Butt Single V Butt Double V Butt Fillet Step 3 Select your weld preparation all variables are mandatories to proceed the calculation WELD FITTING DIMENSIONS Nom Pipe Size In OD Wall Thickness T 90° Elbows 90° Returns 45° Elbows Tees Caps Crosses Stub Ends ST XS XX Long R A Short R A Long R K Short R K B C E C F G 1/2 — — 1 1/2 — 1 15/16 — […]The second solution for drastically reducing the volume of the bevel and consequently the amount of weld metal in the ‘J’ groove preparation Single angle ‘J’ grooves are comprised of an angle that is normally between 5° and 20° a groove radius r and an increase in the land e In actual shop fabrication welding can be in any intermediate position For detailed information on the definition of the various welding positions please consult Appendix E of CSA Standard W59 Welded Steel Construction Metal Arc Welding or AWS A3 0 Standard Welding Terms and Definitions Process mode manual semi automatic machine and auto

Fillet Welds F – This is a weld where two pieces of metal are at an angle in relation to each other often 90 degrees Groove Welds G – This is a weld that is made where two pieces of metal are flush or level in relation to each other Any position that is followed by the letter “G” is a groove weld and “F” is a fillet weld stick / arc welding uphill and more stick welding pipe using tig for root and for fill and cover pass stick welding using rods video shows tee joint tips using rods tig inverters comparison doing tig and stick welding on a mounting bracket The Miller Maxstar stl is a tiny but powerful tig inverter that stick welds too The fitting is welded fully up to the outer edge of the weld bevel The groove weld has a transition weld cap that provides a smooth transition to the main pipe wall The use of excessive weld metal is not allowed A large increase in weld cross section is just as bad as not having enough weld cross section for fittings made from plate Refer to CCTF catalogue “Stainless Steel Welding Fittings SPECIAL METALS High Test h test pipe line welding fittings conforming to CSA Standard CAN3 or MSS SP 75 are available with physical properties to match pipe with 42 46 52 60 65 and over p s i minimum yield Often associated with a groove weld is going to be the weld size This weld size is the depth of penetration you will be getting when applying the weld When a weld is applied we should be melting into the root of the part so our weld should be larger in dimension than the preparation of the joint HK 9DC Strandard auto welding carriage Our company’s multifunction angle weld trolley is wonderful It has many functions It can make the person who isn’t proficient do angle weld easily Chief characters are following Small capacity low gravity center lightweight portable Groove Welding Symbols A groove weld will be used when to parts come together in the same plane These welds will be applied in a butt joint and may have a preparation or not before welding This is the reason there are several types of groove welding symbols The symbols for these grooves are nearly identical to the symbols that represent them 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 Note that the correct weld profile has the following characteristics The fitting is welded fully up to the outer edge of the weld bevel The groove weld has a transition weld cap that provides a smooth transition to the main pipe wall The use of excessive weld metal is not allowed
