The purpose of this study is to identify the key criteria from the perspective of handmade, authenticity and sustainability for purchasing craft items by Indian consumers.

An exploratory qualitative research was conducted on the buying behaviour of Assamese muga mekhela chador (MMC). Data were collected using purposive sampling and video-recorded focus group discussions (FGDs). Output transcripts were content-analysed using the R package RQDI.

Indian consumers largely define crafts as handmade. Results indicate the crucial role of craft design and price. Craft authenticity, craft knowledge and social identity evolved as the key criteria for buying crafts. State intervention in craft certification is demanded. Indian craft consumers lack awareness about sustainable consumption.

India is home to millions of craftspeople and craft buyers. Most of the earlier craft studies focused on the problems of craft production in India. This study contributes to the consumption literature, from the standpoints of authenticity and sustainability, which are often limited to Western consumers. Understanding its own domestic craft market will help Indian policymakers and organisations to reduce export dependency and to tap potential local craft demand.

Friction stir processing (FSP) is overviewed with the process variables, along with the thermal aspect of different metals.

With its inbuilt advantages, FSP is used to reduce the failure in the structural integrity of the body panels of automobiles, airplanes and lashing rails. FSP has excellent process ability and surface treatability with good corrosion resistance and high strength at elevated temperatures. Process parameters such as rotation speed of the tool, traverse speed, tool tilt angle, groove design, volume fraction and increase in number of tool passes should be considered for generating a processed and defect-free surface of the workpiece.

FSP process is used for modifying the surface by reinforcement of composites to improve the mechanical properties and results in the ultrafine grain refinement of microstructure. FSP uses the frictional heat and mechanical deformation for achieving the maximum performance using the low-cost tool; the production time is also very less.

The criteria importance through intercriteria correlation (CRITIC) and range of value (ROV) combined methods were used to determine a single index for all multiple responses.

This paper used cold metal transfer (CMT) and pulse metal-inert gas (MIG) welding processes to study the weld-on-bead geometry of AA2099-T86 alloy. This study used Taguchi's approach to find the optimal setting of the input welding parameters. The welding current, welding speed and contact-tip-to workpiece distance were the input welding parameters for finding the output responses, i.e. weld penetration, dilution and heat input. The L9 orthogonal array of Taguchi's approach was used to find out the optimal setting of the input parameters.

The optimal input welding parameters were determined with combined output responses. The predicted optimum welding input parameters were validated through confirmation tests. Analysis of variance showed that welding speed is the most influential factor in determining the weld bead geometry of the CMT and pulse MIG welding techniques.

The heat input and weld bead geometry are compared in both welding processes. The CMT welding samples show superior defect-free weld beads than pulse MIG welding due to lesser heat input and lesser dilution.
