INTRODUCTIONBharat wagon & engineering co. ltd. An ISO certified company is a PSU. It is engaged in manufacturing of goods wagon for Indian railways.This company was started by an English man Mr. Arthur Butler around 1870 , when industrial revolution was taking place . At this time there where 200-300 workers worked there. Up to April 1946 the company was managed by M/S BALWAR LAWIRE & company limited which transferred.

Press & smithy shopIn this press and smithy shop there are seven open hearth furnaces where coal burns on the bed .On these famous various of parts are heated .The heated part is kept of the anvil with the help of hammer the required shape is firmed. There are many component of this shop.1. Hydraulic press 400t & 250t.2. Press machine 600t3. Power hammer 400 kg &250kg4. Coal fired forge5. Oil fired Furnace6. Blower

cutting SHEARING CUTTING MACHINE On the shearing machine the plate to

be cut should be flat and the thickness should not more than 18mm.

For cutting the flat plate is kept on the bed of the machine and moved manually.

The machine consist of a cutting blade & number of pressing bolts.

As the plate is moved inside the machine the pressing bolts press the plate and keep it rigidly fixed the downward movement of the cutting blade cuts the blade.

WELDING ARC WELDING :- Arc welding is a type of welding that 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.

Template shop There are two types of template area:- 1:-marking template. 2:-checking template.The manufacturing of template is done with the help of design and drawing provided by RDSO LUCKNOW .Also the required allowance for different tools are taken into consideration during marking template.The template here are usually made of mild steel.They are of small thickness about 2.5mm.If a minor fault can create a great fault in the production.

MAINTAINENCE SHOPMaintenance shop is responsible to repair the machining element and give the ability of working as same as before.Maintenance shop responsibilities include:1.Repairing broken windows ,window sashes ,and window locks.2.Repairing broken doorknobs , door closers , and door stops.

STRUCTURAL SHOPCENTER SILL

DESCRIPTION

Centre sill is the part is bears all the weight of the wagon. It is in 3 separate parts which are welded together. Each part is made of 2 separate Z sections, which are welded together. Z-section are welded after they have been drilled and finished for assembling rivets in them in later stage.On the two ends it has Centre filler which actually takes the weight of whole wagon. Each centre filler has Bolster which is fixed with the wheel of wagon. Stepnarsare provided to give strength to the structure. Z-sections

WAGON ASSEMBLY SHOPIn this shop the various component are manufactured in the different shop are assembled and the wagon is completed and then sent to the finishing shop.

Finishing shopAfter assembling the wagon is sent to the finishing shop.In this shop the wagon is brought to the shot blaster chamber.In this chamber small iron particle is allowed to strike on the wagon to remove the extra welding deposit and the rust form on it.In this chamber the working condition are very hazardous.So the workers wear oxygen mask before doing work in side the chamber.After this the wagon is painted and the specification is written and then dispatch to the Indian railway.

I think few minor improvement in its functioning may slightly help in better management of scrap. Better communication link between the workshops and the scrap depot can be developed for faster and efficient transportation of scrap. Computer at workshop and the scrap depot should be linked through networking such that there is no need of advice note and all formalities could be done on computer only. This surely will result in faster scrap management.

DOES ANYONE HAVE ANY QUERIES
