Welders have many job responsibilities and duties while being on the job. ● Read blueprints and drawings and take or read measurements to plan layout and procedures ● Determine the appropriate welding equipment or method based on requirements ● Set up components for welding according to specifications (e.g. cut material with powered saws to match measurements) ● Operate angle grinders to prepare the parts that must be welded ● Align components using calipers, rulers etc. and clamp pieces ● Weld components using manual or semi-automatic welding equipment in various positions (vertical, horizontal or overhead) ● Industrial pipe & elbow welding ● Repair machinery and other components by welding pieces and filling gaps ● Test and inspect welded surfaces and structure to discover flaws ● Maintain equipment in a condition that does not compromise safety

A Lab Technician – Metal Testing is responsible for carrying out metal testing on a variety of metals in a lab. In the process, the individual prepares the lab, testing tools and equipment and metal samples for testing, and carries out various tests as per the approved metal testing methods. The person also carries out minor repair and maintenance of the testing tools and equipment.
A Lab Technician – Radiographic Testing is responsible for preparing the test zone, radiographic testing tools and equipment, test material, and carrying out a variety of radiographic tests. The individual is also responsible for developing the exposed ﬁlms after testing, recording the relevant data and preparing the appropriate reports. The person ensures compliance with the applicable regulations and also carried out minor repair and maintenance of the radiographic testing equipment.
The individual will be able to impart theoretical instructions, demonstrate practical skills, evaluate and grade trainees of Lift & Escalator Mechanic trade in ITIs/ Vocational Training Institutes, industrial workshops, etc.
Machinist will be able to study drawings or measures out sample with appropriate measuring instruments to note different dimensions and sequence of operations required. He/she selects metal piece and marks it or gets it marked for machining operations required, fastens metal in chuck, jig or other fixture and respective tool or cutter, according to sequence of operation, on appropriate machine (lathe, shaper, milling, slotting, drilling, grinding).Checks machine setting or sets it for stipulated machine operations etc.
The individual will be able to impart theoretical instructions, demonstrate practical skills, evaluate and grade trainees of Machinist and Operator Advance Machine Tools trade in industrial workshops, ITIs/Vocational Training Institutes etc.
Grinder, grinds machine tools and cutter to correct specifications by special grinding machines and wheel. Studies drawings and other specifications to understand nature of grinding operation required. Fastens appropriate abrasive wheel to spindle of machine. Mounts cutting tool to be ground on machine using dividing head, jig or fixture as required. Manipulates swivel tables, wheel head and work holding device, guide finger, etc. as necessary to set machine to appropriate angle for grinding desired level on cutting edges of tool selects and sets speed and feed to machine according to nature of work and wheel used. Starts machine, brings rotating grinding wheel in contact with edge of tool and grinds proper angles, clearance, flutes etc. as required on tool or cutter set, frequently checking it with gauge or measuring instrument while grinding to ensure accuracy. Rotates work through proper angle by dividing head or otherwise to set next flute or teeth of tool or cutter for grinding and continues operation. Uses cutting fluid or coolant as found necessary and ensures that no part of work gets burnt or damaged while grinding. Stops machine and removes tool when grinding is completed. Changes grinding wheel and position of tool as and when required. May give final finish to cutting edge by hand using hones. May oil and clean machine. May specialize in grinding a particular type of tool and be designated accordingly. May check ground tool or cutter by shadow projector to ensure accurate finish. Grinder Operator makes metal articles to required specifications using lathe and cutting tools. Studies drawings and other specifications of parts to be made. Selects metal, holds it in chuck, jig or fixture on lathe as required, centres it by manipulating chuck jaws or otherwise using dial indicator or marking block and securely tightens it in position. Selects correct cutting tool, grinds it if necessary and holds it tight in tool post at correct height. Sets feed and speed and starts machine. Manipulates hand wheels or starts automatic controls to guide cutting tool into or along metal. Controls flow of coolant (cutting lubricant) on edge of tool. Arranges gears in machine to obtain required pitch for screw cutting. Calculates tapers and sets machine for taper turning, controls lathe during operation by means of hand wheels and levers and frequently checks progress of cutting with measuring instruments such as calipers and rule, micrometers, etc. Stops machine, removes completed part and checks it further with instruments to ensure accuracy.
Machinist Grinder will be able to grind and smoothen metal surfaces to specified accuracy using one or more type of grinding machines by examining drawings and other specifications for nature of grinding operations required and check progress of grinding with measuring instruments and gauges for accuracyetc.
The individual will be able to impart theoretical instructions, demonstrate practical skills, evaluate and grade trainees of Machinist (Grinder) trade in ITIs/ Vocational Training Institutes, industrial workshops, etc.
