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.
Draughtsman, Mechanical prepares drawings of machines, plants , mechanical components, equipments, etc. from sketches, notes, data or sample for purposes of manufacture or repairs. Takes instructions from Mechanical Engineer and calculates dimensions as required, from available materials (notes, data etc.) or sample. Draws to scale detailed drawings, assembly drawings, showing plan, elevations, sectional views etc. according to nature of work and operations required. Prints (writes) dimensions, tolerances, material to be used and other details to gives clear picture and facilitate understanding. Maintains copies of drawings and makes blue prints. May trace drawings. May design simple mechanical parts. May prepare estimates for materials and labour required. May specialise in making drawings of jigs and tools and be designated accordingly. Create objects on Drawing Space using toolbars, commands and menus in CAD application software and also creating objects on 3D modeling space in CAD viewing printable drawing and plotting them. Plan and organize assigned work and detect & resolve issues during execution. Demonstrate possible solutions and agree tasks within the team. Communicate with required clarity and understand technical English. Sensitive to environment, self-learning and productivity.

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.
Fitter generalizes metal parts to close tolerances and fits and assembles them using hand tools for production or repairs of machines, or other metal products. Studies drawings to understand specification of different parts, fittings or assembles to be made and their functions. Cuts and shapes required parts dimensions and specifications by processes of sawing, chipping, filing, grinding, drilling holes, screw cutting, scrapping etc., Assembles parts by riveting, screwing, pining etc. so as to make complete unit according to drawing. Dismantles or removes worn out, broken or defective parts using hand tools and replaces them by repaired or new ones. Tests completed article to ensure correct performance. May do simple turning of parts on machines and perform welding, brazing, annealing, hardening, tempering and like operations. May specialize in particular type of machine or product and be designated accordingly. May suggested alterations. Sizes metal accurately to required dimension by sawing, chipping, filing, etc, using hand tools for making specimens or finished components. Studies drawing or measures sample to record dimensions of part to be made. Holds specified material in vice and sizes it by processes of sawing, chipping and filing. Measures object while working using foot rules, calipers, gauges etc. and checks for correct filing with square. Gets half-finished object marked or marks it himself using face plate, marking block scriber, vernier, height gauges, vice-blocks, angle plate, sine plate, slip gauges, combination set, etc, depending on accuracies required, to indicate guide lines for finished sizes, holes to be drilled and pitch centres, threads to be cut and other working details as specified in drawing or sample. Clamps object securely in correct position in vice and files it to required dimensions according to punch marks and guide lines frequently measuring it with clippers, micrometer, vernier, gauges etc, Drills holes with hand drill, cuts threads with taps and dies ensuring that they are square or at required angle to base. Measure finished article with dial indicator, micrometer, vernier, height gauges, screw gauges, plug gauges, sine plate slip gauge, etc according to prescribed accuracies. May make parts separately and assemble those screws, rivets, pins, etc. as specified. May check dimension with shadow graph. May be designated as FITTER General according to nature of work done. Plan and organize assigned work and detect & resolve issues during execution. Demonstrate possible solutions and agree tasks within the team. Communicate with required clarity and understand technical English. Sensitive to environment, self-learning and productivity.
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.
