The Horizontal Directional Drilling Process

Downhole mechanical cutting action required for harder soils is provided by downhole hydraulic motors. Downhole hydraulic motors, commonly referred to as mud motors, convert hydraulic energy from drilling mud pumped from the surface to mechanical energy at the bit. This allows for bit rotation without drill string rotation.

Maser - Wikipedia

A maser ( / ˈmeɪzər /, an acronym for microwave amplification by stimulated emission of radiation) is a device that produces coherent electromagnetic waves through amplification by stimulated emission. The first maser was built by Charles H. Townes, James P. Gordon, and Herbert J. Zeiger at Columbia University in 1953.

working metal piece. The shielding gas (generally argon, helium, or carbon dioxide) minimizes contact of the molten metal with air to avoid adverse chemical reactions that would weaken the resulting weld. MIG (Metal Inert Gas, also known as GMAW, Gas Metal Arc Welding) welding uses an aluminum alloy wire as a combined electrode and filler material.

Grinding Machine: Types, Parts, Working & Operations (With PDF)

A grinding machine or grinder is an industrial power tool that uses an abrasive wheel for cutting or removing the m aterial. It is a process of metal cutting by using a rotating abrasive whee l from the surface of the workpiece. Generally, the grinding is finishing operation to show the high surface quality, accuracy of the shape and dimension.

Gas Welding : Principle, Working, Equipment, Application ...

Apr 16, 2017 · Gas welding is a type of liquid state welding process in which fuel gases burns to generate heat. This heat is further used to melt interface surfaces of welding plates which are held together to form a joint. In this process, mostly oxy-acetylene gas is used as fuel gas. This process can be done with or without help of filler material.

• Gas Tungsten Arc Welding (GTAW) – Tungsten (Wolfram) Inert Gas (TIG) Welding – With or without a filler metal – Tungsten melts at 3410°C – Shielding gas: argon, helium or a mixture – All metals (commonly Al and Stainless steels) in a wide range of thickness – Slow and costly but high quality weld for thin sections

How to Weld - MIG Welding : 11 Steps (with Pictures ...

The Gas Tank Assuming you are using a shielding gas with your MIG welder there will be a tank of gas behind the MIG. The tank is either 100% Argon or a mixture of CO2 and Argon. This gas shields the weld as it forms. Without the gas your welds will look brown, splattered and just generally not very nice.


1890s, hydrogen and natural gas were mixed with oxygen for welding, but the oxyacetylene flame achieved significantly higher temperatures. These three welding processes—arc welding, resistance welding, and oxyfuel gas welding—constitute by far the majority of welding operations performed today.


Arm rests, tanks, gas tanks. Types of Blow moulding machine: 1. Extrusion Blow moulding 2. Injection Blow moulding 3. Stretch Blow moulding 1. Extrusion Blow moulding: In extrusion blow molding (EBM), plastic is melted and extruded into a hollow tube (a parison). This parison is then captured by closing it into a cooled metal mold.

Oxyfuel Cutting - Process and Fuel Gases - TWI

Oxy-fuel cutting is a thermal cutting process that uses oxygen and fuel gas (such as acetylene, propane, MAPP, propylene and natural gas) to cut through materials. The oxyfuel process is the most widely applied industrial thermal cutting process because it can cut thicknesses from 0.5mm to 250mm, the equipment is low cost and can be used ...

What kind of equipment is used for gas cutting?

The equipments used for Gas-cutting is similar to that of gas-welding except that the welding torch is replaced by a special designed cutting torch. 1. Gas cutting torch. 2. Pressure regulators. 3. Gas cylinders. 4. Hose and hose fittings. 5. Goggles and glasses.

For smaller plates and sections, machines featuring a range of shearing knives, which can accept the differing section shapes, are available. 2.2.2 Flame Cutting or Burning In this method, the steel is heated locally by a pressurised mixture of oxygen and a combustible gas such as propane, which passes through a ring of small holes in a cutting

Gas-Cutting: Process, Techniques and Advantages | Welding

1. Gas Cutting Torch: A specially designed gas cutting torch is shown in Fig. 7.43. The tip of the cutting torch has a larger centre opening from which a jet of oxygen comes to cut the metal. This central opening surrounded by a set of orifices (generally four) which supply the oxygen-acetylene mixture for pre-heating.

What are the advantages and disadvantages of gas cutting?

Efficiency of Gas-Cutting 3. Equipments 4. Limitations. Apart from using hacksaw, power saw, chisels, etc. for metal cutting operation, gas or oxygen cutting is extensively used now-a-days in industry. (i) It uses oxidizing flame.


Light the gas by means of a suitable sparklighter making sure that the sparklighter is held at right angles to the nozzle. Do not use liquid igniters (such as cigarette lighters) as the vapour/gas combination can be dangerous. Reduce or increase the acetylene supply to the blowpipe valve until the flame just ceases to smoke.
