A trainee attending the course on ‘CO2 welder’ shall be able to read fabrication drawing, examine, clean and clamp parts to be welded. The trainee shall be able to connect work piece with earth cable, welding machine with suitable gas cylinder, regulator, flow meter, and pre-heater when CO2 is used as shielding gas. The trainee shall be able to select suitable wire electrode, feed it to welding CO2 Welding torch through wire feeder, select contact tip gas nozzle and fit into the CO2 welding torch, preheat joints, start the Constant Voltage CO2 welding machine, set suitable welding voltage & wire feed speed and shielding gas flow, produce arc between work piece and continuously fed wire electrode. The trainee also melts the metal and deposit weld beads on the surface of metals or joins metal pieces such as carbon steels, and low alloy steels to a required quality, minimizing distortion and avoiding weld defects.
It involves understanding the customer’s requirement with respect to the mechanical engineering equipment and establish a design brief, further allocate responsibilities and resources to each activity, and ensure that the complete designing process is completed within agreed deadlines and complying with all relevant regulations, identifying design options, evaluation of design options and their presentation in suitable formats, creating detailed design and models using 2D and 3D softwares for design and obtaining design validations from production and maintenance considerations.
It involves select the appropriate equipment and drawing software to use based on the type and complexity of the drawing functions to be carried out and file management and associated customization of installed software including the use of macros- menus and default settings for various kinds of civil work.
It involves select the appropriate equipment and drawing software to use based on the type and complexity of the drawing functions to be carried out and the use of a CAD system linked bills of material- file management and associated customization of installed software including the use of macros- menus and default settings.
It involves select the appropriate equipment and drawing software to make or modify drawings of process flow- piping and instrumentation (P&ID) diagrams and isometric and spool drawings. It will also include orthogonal single and double line arrangement drawings of pipe installation systems and piping layouts..
It covers the general operation- monitoring and adjustment of manual and semi-automatic electroplating processes. It includes preparing and planning for the electroplating operations- pretreatment- volume production and post-treatment activities.
It involves the assembly of the electrical panels-equipment/systems and electronic products- inclusive of components- sub-assemblies- or completed equipment/systems. Along with soldering techniques and anti-static protection techniques assemble with the mechanical equipment.
Involves identifying metals- tools; carrying out fitting and fabrication operations like measuring- marking out- sawing- grinding- drilling- chiseling- threading- tapping- scraping- manual lapping and inspecting of components in order to fit a component as per specifications. It also involves basic oxy-fuel gas cutting and basic manual arc welding as per given instructions and under supervision.
It involves marking out the material for the features to be produced- and then use hand tools- portable power tools- manually operated machine tools and shaping- fitting and assembly techniques appropriate to the operations being performed. The candidate will be expected to check the quality of the workpiece- using measuring equipment
Perform semi automatic flux cored arc welding process for a range of standard welding job requirements and weld different materials from a selection of (carbon steel and stainless steel) in various positions. The welder can prepare various joints including corner, butt, fillet and tee.
It involves preparing the material using appropriate method- setting up forging machines with dies and presses and using forging techniques so that the material forms the shape as per the die. It also involves checking the prepared components for accuracy.
