WELDING DVD SERIES MIG TIG ARC FLUX OXY-ACETYLENE VIDEO

AN IN-DEPTH LOOK AT THE MOST COMMONLY USED TYPES OF WELDING IN THE INDUSTRY TODAY.  THIS INSTRUCTIONAL DVD SERIES COVERS ALL ASPECTS OF TODAY’S MODERN WELDING CAPABILITIES.  INCLUDING STEP-BY-STEP INSTRUCTIONS ON SOME OF THE MOST COMPLEX TASKS A WELDER WOULD ENCOUNTER.  THESE VIDEOS DISPLAY EXTREME CLOSE UPS, DETAILED EXPLANATIONS, AND DEMONSTRATIONS OF THE TASKS AT HAND.  THIS DVD WOULD ALSO BE AN EXCELLENT INVESTMENT FOR SOMEONE LOOKING TO BUY A WELDING OUTFIT.  AFTER VIEWING THE DIFFERENT WELDING PROCESSES, YOU WOULD BE ABLE TO DETERMINE WHICH TYPE OF WELDING OUTFIT WOULD BE BEST FOR YOU.  THE FOLLOWING WELDING/CUTTING PROCESSES ARE DISCUSSED IN THIS SERIES. 

GAS METAL ARC WELDING + FLUX CORE WELDING

THERE ARE A LOT OF SIMILARITIES BETWEEN GAS METAL ARC WELDING (MIG) AND FLUX CORE ARC WELDING, INCLUDING THE USE OF DIRECT CURRENT TO PROVIDE CONSTANT VOLTAGE. VIEWERS WILL ALSO LEARN ABOUT THE DIFFERENT TYPES OF ELECTRODE WIRES USED IN EACH OUTFIT. WIRE FEEDERS ARE DEMONSTRATED ALONG WITH THE SPOOLS THAT FEED THEM - CONTAINING SEVERAL HUNDRED FEET OF ELECTRODE WIRE...ALLOWING WELDERS TO MAKE LONG CONTINUOUS WELDS. STUDENTS WILL SEE HOW TO POSITION THE ELECTRODE AND HOW TO ESTABLISH A GOOD WELD POOL.

GAS TUNGSTEN ARC WELDING

GAS TUNGSTEN ARC WELDING OR TIG WELDING REPRESENTS SPECIAL SAFETY CONCERNS. VIEWERS ARE WARNED OF THE SUFFOCATION HAZARDS PRESENT WHEN WORKING WITH INERT GASES AND WHY GOOD VENTILATION IS REQUIRED. THE VIDEO ALSO PROVIDES EXPLANATION OF HOW TIG WELDING DIFFERS FROM OTHER TYPES OF WELDING.  ELECTRODE LEADS, HOSES, REGULATORS AND COLLETS ARE DEMONSTRATED AND EXPLAINED AS WELL AS THE USE OF THE POST FLOW TIMER TO PROTECT THE WELD FROM CONTAMINATION. ALSO DISCUSSED ARE USING THE CORRECT COLLET SET AND ELECTRODE SIZE AND TYPE NEEDED FOR THE JOB.

OXYFUEL WELDING PROCESS

OXYFUEL WELDING IS CLEARLY EXPLAINED AND DEMONSTRATES THE CAREFUL AND SAFE METHOD OF USING THE COMBINATION OF ACETYLENE AND OXYGEN GAS CYLINDERS. PRESSURE REGULATORS, CHECK VALVES AND HOSES AND FITTINGS ARE DEMONSTRATED AS WELL AS TORCH TUBES AND TIPS.  CLEAR INSTRUCTIONS ON IGNITION, USE OF THE OUTFIT AND SHUTTING DOWN ARE PROVIDED ALONG WITH TIPS ON FLAME ADJUSTMENT AND METHODS TO DIRECT IT TO THE WORK AREA. ALSO DEMONSTRATED ARE VARIOUS WELDING TECHNIQUES AND TYPES OF WELDS.

THE OXY-ACETYLENE WELDING PROCESS

OXYACETYLENE WELDING, COMMONLY REFERRED TO AS GAS WELDING, IS A PROCESS, WHICH RELIES ON COMBUSTION OF OXYGEN AND ACETYLENE. WHEN MIXED TOGETHER IN CORRECT PROPORTIONS WITHIN A HAND-HELD TORCH OR BLOWPIPE, A RELATIVELY HOT FLAME IS PRODUCED WITH A TEMPERATURE OF ABOUT 3,200 DEG.C. THE CHEMICAL ACTION OF THE OXYACETYLENE FLAME CAN BE ADJUSTED BY CHANGING THE RATIO OF THE VOLUME OF OXYGEN TO ACETYLENE. WHEN CARRYING OUT FUSION WELDING THE ADDITION OF FILLER METAL IN THE FORM OF A ROD CAN BE MADE WHEN REQUIRED. THE PRINCIPAL TECHNIQUES EMPLOYED IN OXYACETYLENE WELDING ARE LEFTWARD, RIGHTWARD AND ALL-POSITIONAL RIGHTWARD. THE FORMER IS USED ALMOST EXCLUSIVELY AND IS IDEALLY SUITED FOR WELDING BUTT, FILLET AND LAP JOINTS IN SHEET THICKNESSES UP TO APPROXIMATELY 5MM. THE RIGHTWARD TECHNIQUE FINDS APPLICATION ON PLATE THICKNESSES ABOVE 5MM FOR WELDING IN THE FLAT AND HORIZONTAL-VERTICAL POSITION. THE ALL-POSITIONAL RIGHTWARD METHOD IS A MODIFICATION OF THE RIGHTWARD TECHNIQUE AND IS IDEALLY SUITED FOR WELDING STEEL PLATE AND IN PARTICULAR PIPE WORK WHERE POSITIONAL WELDING, (VERTICAL AND OVERHEAD) HAS TO BE CARRIED OUT. THE RIGHTWARD AND ALL- POSITIONAL RIGHTWARD TECHNIQUES ENABLE THE WELDER TO OBTAIN A UNIFORM PENETRATION BEAD WITH ADDED CONTROL OVER THE MOLTEN WELD POOL AND WELD METAL. MOREOVER, THE WELDER HAS A CLEAR VIEW OF THE WELD POOL AND CAN WORK IN COMPLETE FREEDOM OF MOVEMENT. THESE TECHNIQUES ARE VERY HIGHLY SKILLED AND ARE LESS FREQUENTLY USED THAN THE CONVENTIONAL LEFTWARD TECHNIQUE.

JOINING – WELDING & SOLDERING

THIS SERIES CONSISTS OF THE VISUAL TEACHING OF PRINCIPLES, WORKSHOP DEMONSTRATIONS AND EXAMPLES OF THE PRACTICAL APPLICATION OF THESE PRINCIPLES IN A VARIETY OF ENGINEERING SITUATIONS.  PROCESSES COVERED ARE SOLDERING, ARC/MMA WELDING, SPOT/RESISTANCE WELDING, GAS WELDING, BRAZING. 

ARC WELDING

ARC WELDING USES A WELDING POWER SUPPLY TO CREATE AN ELECTRIC ARC BETWEEN AN ELECTRODE AND THE BASE MATERIAL TO MELT THE METALS AT THE WELDING POINT. THEY CAN USE EITHER DIRECT (DC) OR ALTERNATING (AC) CURRENT, AND CONSUMABLE OR NON-CONSUMABLE ELECTRODES.  THE PROCESS OF ARC WELDING IS WIDELY USED BECAUSE OF ITS LOW CAPITAL AND RUNNING COSTS.

WELDING PROCESSES

THE WELDING PROCESS COVERS TOPICS SUCH AS:  RIVETING, BRAZING, SOLDERING, FORGED, GAS, ACETYLENE, ELECTRIC ARC/ M.M.A, SUBMERGED ARC, PLASMA, TIG, MIG, SPOT, RESISTANCE, FLASH, AND FRICTION.

WELDING WITH ELECTRODES:

THIS PROGRAM ON WELDING WITH ELECTRODES INCLUDES:  BUTT WELDING, LAP JOINTS, VERTICAL BUTT WELDING, ROOT AND CAPPING RUNS, WELDING PIPELINES BOTH INDOORS AND OUTDOORS.    

OXY-ACETYLENE CUTTING

THE OXY-ACETYLENE CUTTING PROCESS IS ACHIEVED BY BLOWING AWAY THE MOLTEN MATERIAL, WHICH IS MELTED BY THE COMBUSTION HEAT OF ACETYLENE GAS AND OXYGEN. GENERALLY, ONLY STEEL MATERIAL IS CUT USING THIS PROCESS AND MATERIAL OF REMARKABLE THICKNESS CAN BE CUT. FIXED HEAD AIR-CARBON ARC CUTTING AND GOUGING ARE ALSO EXPLAINED. 

ALL VIDEOS ARE PRODUCED ON ONE DVD WITH INTERACTIVE MENUS FOR EASY REVIEW OF SPECIFIC TOPICS.  THIS DVD WILL BE SHIPPED IN ITS ORIGINAL SOFT POLY CASE.  IF YOU WOULD LIKE TO GET YOUR HANDS ON THIS WELDING INSTRUCTIONAL VIDEO SERIES RIGHT AWAY, EMAIL US FOR MORE INFORMATION.
